I believe you have already mentioned the solution, given that your phone is currently in the Technical Preview - use the recovery tool or perform a factory reset.

P.S.#1 The Ask A Question forum is reserved for guests and for time-pressing matters for members; members are strongly encouraged to post their concerns in the respective forums.

P.S.#2 Contrary to popular belief, posting more than one thread about the same topic in different forums may actually be inefficient in arriving at a consistent solution or advise with regards to the concern at hand. In addition, doing so creates fragmentation - both for the user and for other users who may want to refer to the post in the future for reference.

Threads Merged.
